Fluoride Complexation of Element 104, Rutherfordium (Rf), Investigated by Cation-exchange Chromatography

We report on new and much more precise cation-exchange data of element 104, rutherfordium (Rf), in the fluoride ion concentration [F−] range of 5.29×10−5−1.04×10−3 M. The result based on one-atom-at-a-time chemistry clearly demonstrates that the distribution coefficients (Kd) decrease with increasin...

Zusammenfassung:We report on new and much more precise cation-exchange data of element 104, rutherfordium (Rf), in the fluoride ion concentration [F−] range of 5.29×10−5−1.04×10−3 M. The result based on one-atom-at-a-time chemistry clearly demonstrates that the distribution coefficients (Kd) decrease with increasing [F−], suggesting successive fluoride complexation of Rf. The complexation of Rf is briefly discussed in terms of fully relativistic density functional calculation theory.
